Ep. 6 Star Classification Part 2: Cannon and Classification

Second in a two-part series about stars and how we classify them. Beginning with the lifecycle of stars, which is what classifying stars is all about, I then talk about the various ways we've chosen to interpret observational data on stars, from observing the bright sky-dots to evaluating how bright they are by comparing them to each other, and all the new things we can do with CCD imaging. Hear about pre- and post-telescope star catalogs and especially hear about Annie Jump Cannon and how she formed the basis for the star catalog standard we use today.
